The term "power tool" in the warnings refers to your mains-operated
(corded) power tool or battery-operated (cordless) power tool.
Work Area Safety
• Keep work area clean and well lit. Cluttered or dark areas invite
accidents.
• Do not operate power tools in explosive atmospheres, such as in the
presence of flammable liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
• Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.
Electrical Safety
• Power tool plugs must match the outlet. Never modify the plug in any way.
Do not use any adapter plugs with earthed (grounded) power tools.
Unmodified plugs and matching outlets will reduce the risk of electric
shock.
• Avoid body contact with earthed or grounded surfaces such as pipes,
radiators, ranges and refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
• Do not expose power tools to rain or wet conditions. Water entering a
power tool will increase the risk of electric shock.
• Do not abuse the cord. Never use the cord for carrying, pulling or
unplugging the power tool. Keep cord away from heat, oil, sharp edges or
moving parts. Damaged or entangled cords increase the risk of electric
shock.
• When operating a power tool outdoors, use an extension cord suitable for
outdoor use. Use of a cord suitable for outdoor use reduces the risk of
electric shock.
• If operating a power tool in a damp location is unavoidable, use a ground
fault circuit interrupter (GFCI) protected supply. Use of a GFCI reduces
the risk of electric shock.
Personal Safety
• Stay alert, watch what you are doing and use common sense when
operating a power tool. Do not use a power tool while you are tired, ill, or
under the influence of drugs, alcohol or medication. A moment of
inattention while operating power tools may result in serious personal
injury.

• Use personal protective equipment. Always wear eye protection.
Protective equipment such as dust mask, non-skid safety shoes, hard
hat, or hearing protection used for appropriate conditions will reduce
personal injuries.
• Prevent unintentional starting. Ensure the switch is in the off-position
before connecting to power source and/or battery, picking up or carrying
the tool. Carrying power tools with your finger on the switch or energizing
power tools that have the switch on invites accidents.
• Remove any adjusting key or wrench before turning the power tool on. A
wrench or a key left attached to a rotating part of the power tool may
result in personal injury.
• Do not overreach. Keep proper footing and balance at all times. This
enables better control of the power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or jewelry. Keep your hair,
clothing and gloves away from moving parts. Loose clothes, jewelry or
long hair can be caught in moving parts.
• If devices are provided for the connection of dust extraction and collection
facilities, ensure these are connected and properly used. Use of dust
collection can reduce dust-related hazards.
• Do not let familiarity gained from frequent use of tools allow you to
become complacent and ignore tool safety principles. A careless action
can cause severe injury within a fraction of a second.
Proper Clothing
Wear snug-fitting, durable clothing:
• Pants should have long legs, shirts should have long sleeves.
• DO NOT WEAR SHORTS.
• DO NOT WEAR TIES, SCARVES, JEWELRY, or clothing with loose or
hanging items that could become entangled in moving parts or
surrounding growth.
• Keep clothing buttoned or zipped, and keep shirt tails tucked in.
• Wear sturdy work shoes with nonskid rubber soles.
• DO NOT WEAR OPEN TOED SHOES.
• DO NOT OPERATE UNIT WITH BARE FEET.

Power Tool Use and Care
• Do not force the power tool. Use the correct power tool for your
application. The correct power tool will do the job better and safer at the
rate for which it was designed.
• Do not use the power tool if the switch does not turn it on and off. Any
power tool that cannot be controlled with the switch is dangerous and
must be repaired.
• Disconnect the plug from the power source and/or the battery from the
power tool before making any adjustments, changing accessories, or
storing power tools. Such preventive safety measures reduce the risk of
starting the power tool accidentally.
• Store idle power tools out of the reach of children and do not allow
persons unfamiliar with the power tool or these instructions to operate the
power tool. Power tools are dangerous in the hands of untrained users.
• Maintain power tools and accessories. Check for misalignment or binding
of moving parts, breakage of parts and any other condition that may affect
the power tool’s operation. If damaged, have the power tool repaired
before use. Many accidents are caused by poorly maintained power tools.
• Keep cutting tools sharp and clean. Properly maintained cutting tools with
sharp cutting edges are less likely to bind and are easier to control.
• Use the power tool, accessories and tool bits etc. in accordance with
these instructions, taking into account the working conditions and the
work to be performed. Use of the power tool for operations different from
those intended could result in a hazardous situation.
• Keep handles and grasping surfaces dry, clean, and free from oil and
grease. Slippery handles and grasping surfaces to not allow for safe
handling and control of the tool in unexpected situations.
Battery Tool Use and Care
• Recharge only with ECHO eFORCE™ 56V battery series chargers. A
charger that is suitable for one type of battery may create a risk of fire
when used with another battery.
• Use only with ECHO eFORCE™ 56V battery series. Use of any other
battery may create a risk of injury and fire.
• When battery is not in use, keep it away from other metal objects, like
paper clips, coins, keys, nails, screws or other small metal objects, that
can make a connection from one terminal to another. Shorting the battery
terminals together may cause burns or a fire.

• Under abusive conditions, liquid may be ejected from the battery; avoid
contact. If contact accidentally occurs, flush with water. If liquid contacts
eyes, additionally seek medical help. Liquid ejected from the battery may
cause irritation or burns.
• Do not open or destroy the battery. Electrolytes contained within the
battery are corrosive and may cause damage to eyes or skin if released.
It may be toxic if swallowed.
• Exercise care in handling batteries to avoid shorting the battery with
conducting materials such as rings, bracelets, keys, etc. The battery or
conductor may overheat and cause burns if contact with said materials is
made.
• Do not use a battery or tool that is damaged or modified. Damaged or
modified batteries may exhibit unpredictable behavior resulting in fire,
explosion or risk of injury.
• Do not expose a battery or tool to fire or excessive temperature.
Exposure to fire or temperature above 130°C (266°F) may cause
explosion.
• Follow all charging instructions and do not charge the battery or tool
outside the temperature range specified in the instructions. Charging
improperly or at temperatures outside the specified range may damage
the battery and increase the risk of fire.
Service
• Have your power tool serviced by a qualified repair person using only
identical replacement parts. This will ensure that the safety of the power
tool is maintained.
